Milk Rainbow Science Experiment

This STEAM experiment is so simple to set up you probably already have all the supplies you need in your kitchen right now!

Materials:

• White plate or shallow bowl
• Food coloring
• Small white washcloth
• Hand soap
• Small glass of milk

 

Instructions:

1. Place the white plate or shallow bowl on a flat surface.
2. Pour a small amount of milk onto the plate or bowl to line the bottom.
3. Begin to place drops of different colors of food coloring all over the surface of the milk on the plate. Leave space between the dots for a better outcome.
4. Fold a small white washcloth in half lengthwise, and then roll it up into a long cylindrical shape.
5. Dip the bottom of the rolled washcloth into some hand soap.
6. Place the washcloth soap side down into the center of the milk covered plate.
7. Watch as the colors begin to magically swirl and move, radiating out from the washcloth in the middle of the plate. Observe how the colors are sucked up into the bottom of the white washcloth, and change its color.

How Does the Milk Rainbow Happen?

While the kids might think it’s pure magic, it’s really all about a little bit of science and gravity. The milk is the main base that keeps the food coloring in smaller sections. Then, when you put the soapy end of the washcloth into the milk mixture, it starts soaking up that milk and the food coloring follows. 

This not only creates a “growing rainbow” look right up the washcloth but it creates an illusion of magic as well. 

How can you tie in this milk rain science experiment to learn more about the weather?

Learning about rainbows and how they form is always fun. Once this experiment is over you can always head out the door and talk about the various weather patterns or clouds up in the sky. It’s so much fun to combine real-world activity with creativity! 

 

 

Don’t let the magic of science stop here!
